Oil burner

ABSTRACT

An oil burner is disclosed to include a burner body holding a candle on its bottom side for burning, and an oil pan, which has a recessed top open chamber for holding an essential oil, a bottom partition wall supported on the burner body above the candle, an air chamber defined between the recessed top open chamber and the bottom partition wall, and a plurality of air holes cut through the bottom partition wall through which the flow of hot air produced during burning of the candle enters the air chamber to heat the recessed top open chamber evenly and to cause the essential oil to evaporate gradually.

BACKGROUND OF THE INVENTION

(a) Field of the Invention

The present invention relates to oil burners and more particularly to a heating temperature controllable oil burner, which uses a heat source (candle) at the bottom side to heat an essential oil carried on the top, thereby working as a night lamp that emits a pleasant smell.

(b) Description of the Prior Art

Stress at work or the tension in life may cause occupational ill health. Therefore, modern people need to relax the body physically, minimizing the impact of stress and improving organizational performance. It is reported that special aromatic plant smells help release stress, alleviate tension, and make life pleasant. Many essential oils concentrated from various plants are commercially available. These essential oils may be burned in an oil burner (night lamp for essential oil) for aromatic treatment of the body and the mind.

Conventional oil burners (night lamps for essential oil) are commonly made out of ceramics in the shape of a container for carrying water and an essential oil. When in use, a candlestick or the like is set beneath the container to heat the container. According to this design, the container is directly heated by the heat source, and the essential oil that is carried in the container will soon be burned out. Further, the surface temperature of the product would soon become high due to direct heating. When a person touches the product or when the product falls down accidentally, a potential injury may happen.

SUMMARY OF THE INVENTION

The present invention has been accomplished under the circumstances in view. According to one aspect of the present invention, the heating temperature controllable oil burner comprises a burner body and an oil pan. The burner body holds a candle on the bottom side for burning. The oil pen is supported on the top side of the burner body above the candle, having a recessed top open chamber for holding an essential oil, a bottom partition wall, an air chamber defined between the recessed top open chamber and the bottom partition wall, and a plurality of air holes cut through the bottom partition wall through which the flow of hot air produced during burning of the candle enters the air chamber to heat the recessed top open chamber evenly and to cause the essential oil to evaporate gradually.

According to another aspect of the present invention, by means of controlling the number and opening status of the air holes on the bottom partition wall of the oil pan, the heating temperature that is applied to the essential oil can be controlled.

According to still another aspect of the present invention, the oil pan and the burner body can be respectively molded from a ceramic material and then burned together. Alternatively, the oil pan and the burner body can be separately made and detachably attached together.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIGS. 1 and 2, a heating temperature controllable oil burner in accordance with the present invention is shown comprised of a burner body 1 and an oil pan 2. The oil pan 2 is adapted to hold an essential oil 5 (see FIG. 3). Water may be added to the oil pan 2 to dilute the essential oil 5. A heat source, for example, a candle 3 is put in the burner body 1 to heat the oil pan 2, causing the essential oil 5 to evaporate and to provide a pleasant smell.

The burner body 1 may be made in the shape of any of a variety of hollow containers. According to this embodiment, the burner body 1 is a hollow cylindrical member having an access hole 11 on the vertically extending peripheral wall at a selected location, and a plurality of air vents 12 cut through the vertically extending peripheral wall to admit light and air.

Referring to FIGS. 4 and 5 and FIGS. 1˜3 again, the oil pan 2 is a hollow vessel having a recessed top open chamber 21 that carries the essential oil 5, a bottom partition wall 22, an air chamber 23 defined between the recessed top open chamber 21 and the bottom partition wall 22, and a plurality of air holes 221 cut through the bottom partition wall 22 in air communication with the air chamber 23.

Referring to FIGS. 7 and 8, the oil pan 2 can be made having a wavelike rim 24, showing the shape of a flower that provides an aesthetic effect.

Referring to FIGS. 1 and 4 again, the burner body 1 and the oil pan 2 are respectively molded from ceramics and fastened together and then burned into the desired finished product.

FIG. 6 shows an alternate form of the heating temperature controllable oil burner. According to this embodiment, the heating temperature controllable oil burner comprises a container 4, a burner body 1′ which is an upright bracket suspended in the container 4 and holding a heat source, for example, a candle 3, on the bottom side, and an oil pan 2 supported on the top side of the burner body 1′ to hold an essential oil 5.

Referring to FIGS. 3 and 6, when the candle 3 is burning in the burner body 1 or 1′, a flow of hot air is produced and soaring into the air chamber 23 through the air holes 221 on the bottom partition wall 22 of the oil pan 2 to heat the bottom side of the recessed top open chamber 21 evenly, thereby causing the essential oil 5 to evaporate gradually. Because the invention uses a flow of hot air to heat the bottom side of the recessed top open chamber 21 of the oil pan 2, the essential oil 5 will not be vaporized rapidly. Because the flame of the candle 3 is not used to heat the oil pan 2 directly, the surface temperature of the oil pan 2 will not be so high as to cause injuries when the surface of the heating temperature controllable oil burner is touched accidentally.

Further, because the flow of hot air passes through the air holes 221 on the bottom partition wall 22 into the air chamber 23 to heat the recessed top open chamber 21, the rate of the flow of hot air entering the air chamber 23 is controllable through adjusting the number and opening status of the air holes 221.

A prototype of heating temperature controllable oil burner has been constructed with the features of FIGS. 1˜6. The heating temperature controllable oil burner functions smoothly to provide all of the features discussed earlier.

Although particular embodiments of the invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.
